5.56 or 7.62? A compromise may be the best - Page 5

We are talking about the 7.62 X 51 right? Because an intermidiate cartridge of 7.62 x 51 and .223 Nato (5.56 x 45) has been around for about 60 years. Remember the 7.62 x 39R ? I was wondering wouldn't it fit for this intermediate purpose? Or is it too inaccurate at significant distance? Or some other draw back.

Yes, Vitaly, I was referring to the 7.62x51...

The 7.62x39R is a great round for close range work, but is very inaccurate at anything over 200 meters....where the 7.62x51 REALLY shines. The 5.56 is very accurate at 200M, but ballistically, it is a dud at those ranges.It simply cust right through targets without any significant damage or knock down. For suppressive fire, you really can't beat the 5.56, because of the sheer amounts of ammo one man can carry. If you are in a situation where you need to take out enemy directly and your goal is not to keep their heads down while your mates manuever, then the 7.62x51 is good.

I have another question, Do you think that the 7.62 x 39 round is inaccurate do to the cartridge itself or just the fact that the most commonly used platform for it is inaccurate. As in, would the cartridge be accurate in a weapon such as the CZ 527 Carbine ( http://www.cz-usa.com/01.detail.php?id=15 ) ?

Don't use inaccurate eastern AKs since their barrels and iron sights are simply crap for any use which needs accuracy, the round itself isn't bad at all when used in right weapon. RK95 and 62 hits a coin at range 300m for example.

Only by an accident

The sight issue simply is a matter of preference, I got more used to the Ak style sights by using PKM. I never really liked the diopter sight in the first place or I was just so lousy shooter with Rk.
I've heard that during desert storm U.S soldiers regularily engaged enemy troops out of 500 meters away with M16, I guess it could be done since the 5.56mm bullet has very flat trajectory but its quite prone to wind effects

"Only by an accident "

Guess who was the best marksmanship during NCO course? RK62, 5 shots 45points at 300m, iron sights. 8)

AK sights are mostly useless at ranges over 100m compared to "hole sights".

"I've heard that during desert storm U.S soldiers regularily engaged enemy troops out of 500 meters away with M16"

500m is quite long range to engage and even hit with iron sights.

45 points at 300 meters, that's just awesome I was having tough time hitting the target plate itself with Rk at that range, but this clearly shows a gun is just as accurate as the person firing it.

Nope, awesome was to win with that result. The second best got 44p, so i was lucky sob, but 1st position is 1st position anyway. 8)

RKs are first class to shoot, rest is up to shooter himself. Usually i have had problems to adjust my sights correctly and those usual 5+3 targeting shots are too less IMO. Good hits don't help if they aren't inside 10 radius.

I have to say, the 7.62x39 round itself is OK. It doesn't have wonderful ballisitics but does what it does, better than most. I still wouldn't trust it past 200 or 300 meters. Regardless of weapon.

The 5.56 has a VERY flat trajectory and could well reach out and do serious damage at 500 meters, but don't expect to see great ballistics, it will simply pass straight through soft targets. If you have to go to 500 meters, get a 7.62NATO of sorts....GPMG or DM.

That is correct, and the difference is due to the weapon sight and the accessory sights that are used. The accuracy of a weapon increases with the increase in the sight radius i.e the distance between the rear and fore sight.
A 7.62x51mm round or 7.62x39mm can also hit a target at 500 mtrs.
